AFR looks great. Have scanned throught the help file and not sure how to do this. I just need to use afr in command line mode to s&r a bunch of .html files to replace a given string with multiple lines from a file. For example: search all files in given directory for "string-a" and replace with all text from replace.txt which contains:

this is line 1 which could contain a ton of html code, asp code, java code
this is line 2, more of the same
this is line 3, more of the same
etc.
